FIELD OF THE DISCLOSURE

The disclosure relates to exercise devices and more particularly to mobile exercise devices.

BACKGROUND

Athletes of all levels of ability may invest significant time and effort into conditioning their bodies to achieve the best results possible in their associated sports. For those particular sports involving leg strength, conditioning of leg muscles may be desirable. Furthermore, individuals with leg injuries and/or in need of gait correction also may invest significant time and effort into carefully rehabilitating affected leg muscles.

SUMMARY

The subject matter of this application may involve, in some cases, interrelated products, alternative solutions to a particular problem, and/or a plurality of different uses of a single system or article.

One example embodiment of the present invention provides an exercise apparatus including a leg binding positionable on a user's leg, an anchoring device positionable on the user's torso, and a resistive element configured to operatively couple the leg binding with the anchoring device, wherein the resistive element has a length that is sufficient to allow the resistive element to pass from the user's leg, over the user's shoulder, and to the anchoring device. In some cases, the leg binding includes an upper leg cuff positionable on an upper portion of the user's leg and a lower leg cuff positionable on a lower portion of the user's leg. In some such cases, the upper and lower leg cuffs are operatively coupled with one another. In some example instances, the anchoring device includes at least one of a belt positionable about the user's waist, a harness positionable about the user's torso, and/or a shoulder pad including a channel configured to direct the resistive element over the user's shoulder. In some other example instances, the resistive element includes at least one of an elastomeric member, a spring member, a hydraulic member, and/or a pneumatic member. In some yet other example instances, the resistive element includes at least one of an elastomeric band, sheet, strand, strap, braid, and/or tube. In some cases, the resistive element has an adjustable length. In some cases, the resistive element has an adjustable resistance level. In some such cases, the resistance level is capable of extemporal/on-the-fly adjustment.

Another example embodiment of the present invention provides a method of exercising, the method including affixing a resistive element of a given resistance level to a user's leg, passing a portion of the resistive element over the user's shoulder, anchoring the resistive element to a portion of the user's torso, and causing the user to engage in movement of the leg. In some cases, the method further includes affixing the resistive element to the user's other leg and passing a portion of the resistive element over the user's other shoulder. In some example instances, movement of the leg includes walking, jogging, running, overspeed training, cycling, skiing, skating, rowing, or jumping. In some other example instances, movement of the leg is performed in a reverse direction. In some cases, the method further includes adjusting the resistance level of the resistive element. In some such cases, adjusting the resistance level includes at least one of exchanging the resistive element for a resistive element of a different resistance level, changing an effective length of the resistive element, and/or utilizing a plurality of resistive elements. In some example instances, movement of the leg includes at least one of a concentric reaction in the user's gluteus muscles, a concentric reaction in the user's hamstring muscles, an eccentric reaction in the user's hip flexor muscles, extension of the user's hip joint, acceleration of knee drive, and/or a hip flexion concentric reaction. In some other example instances, movement of the leg occurs absent any anchoring provided by an external object or person.

Another example embodiment of the present invention provides an exercise system including a first leg binding including a first upper leg cuff positionable on an upper portion of a user's first leg and a first lower leg cuff positionable on a lower portion of the user's first leg, wherein the first upper leg cuff and the first lower leg cuff are operatively coupled with one another, a second leg binding including a second upper leg cuff positionable on an upper portion of the user's second leg and a second lower leg cuff positionable on a lower portion of the user's second leg, wherein the second upper leg cuff and the second lower leg cuff are operatively coupled with one another, an anchoring device positionable on the user's torso, and a resistive element configured to operatively couple each of the first leg cuff and the second leg cuff to the anchoring device, the resistive element passing over the user's shoulder. In some cases, the system further includes a resistance adjustment component configured to permit adjustment of a resistance level of the resistive element. In some cases, the anchoring device includes at least one of a belt positionable about the user's waist, a harness positionable about the user's torso, and/or a shoulder pad including a channel configured to direct the resistive element over the user's shoulder.

DETAILED DESCRIPTION

Techniques and structure are disclosed for providing and using an exercise device which is mobile and self-contained. In some instances, the device may include a binding positionable on a user's leg, an anchoring device positionable on the user's torso, and a resistive element which operatively couples the leg binding to the anchoring device. In some such instances, the resistive element may be directed over one or more of the user's shoulders. In some cases, the device can be configured to be used on both of a user's legs. In some instances, the device may be used to exercise (e.g., develop, train, work out, exert, condition, etc.) a user's leg muscles, for example, without outside or otherwise external support/anchoring (e.g., from a person or other stationary object). Numerous configurations and variations will be apparent in light of this disclosure.

General Overview

Existing exercise devices which focus on conditioning leg muscles normally require either a willing participant or a sufficiently stationary and secure object to assist in externally stabilizing and activating the resistance load of such devices when in proper use. As such, these devices are precluded from mobility and self-contained functioning.

Thus, and in accordance with an embodiment of the present invention, techniques and structure are disclosed for providing and/or using a mobile exercise device, for example, to exercise (e.g., develop, train, work out, exert, condition, etc.) a user's leg muscles. In accordance with an embodiment, a mobile exercise device provided as disclosed herein may be used to provide resistance through any portion of the full range of motion of a user's leg. Also, and in accordance with an embodiment, the level of resistance experienced by the user may be adjustable at any time during use. Furthermore, and in accordance with an embodiment, the device may be designed to be self-contained, requiring no external assistance or intervention. In some example cases, the device may be lightweight and portable, allowing the user to use the device anywhere and/or under any conditions. In some embodiments, a mobile exercise device provided as described herein may be configured, for example, to permit unidirectional and/or multidirectional movement and/or use. A device provided using the disclosed techniques may be worn, in part or in whole: (1) externally by the user; and/or (2) underneath the user's clothing. In some example instances, the device may be used during a standard athletic practice including routine sprints and practice drills.

In accordance with an embodiment, a mobile exercise device provided using the disclosed techniques can be utilized, for example, to develop and/or condition a user's muscles for any of a wide range of sports, activities, hobbies, etc., for which it may be desirable to exercise one's leg muscles. Some example athletic activities may include, but are not limited to, walking, jogging, running, cycling, skiing, skating, rowing, jumping, and/or any other suitable activities (e.g., overspeed training), which will be apparent in light of this disclosure.

In some cases, and in accordance with an embodiment, a mobile exercise device provided using the disclosed techniques can be utilized, for example: (1) for rehabilitation of a user's leg muscles; and/or (2) to adjust (e.g., correct, perfect, etc.) a user's gait. In accordance with an embodiment, use of the disclosed mobile exercise device can promote improved knee support and thus, in some example instances, minimize or otherwise reduce the likelihood of developing ligament-related injuries, problems, and/or complications.

In accordance with an embodiment, use of the disclosed mobile exercise device during physical activity can result in an increase in the heart rate of the user. For example, in some cases, the user may experience an increase in heart rate in the range of 20-30 beats per minute. Also, and in accordance with an embodiment, use of the disclosed mobile exercise device can result in an increase in the metabolic rate of the user. For example, in some cases, the user may experience an increase in metabolic rate in the range of 30-40%, as compared to the same workout performed without using the device.

In accordance with an embodiment, use of the disclosed mobile exercise device can result in improved (e.g., better or otherwise more complete) extension of the user's leg muscles. In some such instances, and in accordance with an embodiment, this may provide better results for the user in the course of exercising (e.g., developing, training, working out, exerting, conditioning, etc.) the user's leg muscles. Results have shown that use of the device can, for example, increase a user's running speed and/or jumping distance. For instance, after having several test subjects use the device for a distance of approximately 100 yards, the users' average completion speed of a 10-yard dash was shown to be about 0.06 seconds faster. In some other instances, after using the device, the users' single leg triple jump distance increased an average of about eight inches.

Furthermore, and in accordance with an embodiment, a mobile exercise device provided using the disclosed techniques can be configured, for example: (1) as a partially/completely assembled mobile exercise device; and/or (2) as a kit or other collection of discrete components (e.g., leg bindings, resistive elements, anchoring devices, etc.) which may be operatively coupled as desired to provide a mobile exercise device.

Structure and Operation

FIG. 1 is a perspective view of a mobile exercise device 100 configured in accordance with an embodiment of the present invention. As can be seen, mobile exercise device 100 may include, for example, one or more leg bindings 110 (e.g., which may be operatively coupled with a portion of a user's leg), one or more anchoring devices 130 (e.g., which may be operatively coupled with a user's waist, torso, etc.), and one or more resistive elements 150 which may be configured to operatively couple a given leg binding 110 with a given anchoring device 130. As will be appreciated in light of this disclosure, device 100 may include additional, fewer, and/or different elements or components from those here described (e.g., an optional resistance adjustment component 170, discussed below with reference to FIG. 6; etc.), and the claimed invention is not intended to be limited to any particular device configurations, but can be used with numerous configurations in numerous applications.

FIG. 2 is a side perspective view of a mobile exercise device 100 configured in accordance with an embodiment of the present invention. As can be seen, leg binding 110 may include, for example, an upper leg cuff 112, which may be configured, in some example embodiments, to be positionable anywhere along the length of a user's upper leg. For instance, upper leg cuff 112 may be positionable: (1) just above the user's knee; (2) about the user's upper thigh; and/or (3) at any position there between. In some cases, upper leg cuff 112 may include, for example, one or more clips, rings, and/or other receiving sites disposed thereon for attaching to and/or slidably guiding resistive element 150.

As can further be seen, leg binding 110 may include, for example, a lower leg cuff 114, which may be configured, in some example embodiments, to be positionable anywhere along the length of a user's lower leg. For instance, lower leg cuff 114 may be positionable: (1) just below the user's knee; (2) below and/or about the user's ankle; and/or (3) at any position there between. In some cases, lower leg cuff 114 may include, for example, one or more clips, rings, and/or other receiving sites disposed thereon for attaching to and/or slidably guiding resistive element 150.

In accordance with an embodiment, a given leg cuff 112 and/or 114 may be securable and/or fastenable to a user's leg. For example, in some cases, at least one of upper leg cuff 112 and/or lower leg cuff 114 may be fastenable about the user's leg via one or more fasteners 116. In some embodiments, a fastener 116 may be a hook-and-loop fastener operatively coupled (e.g., attached to and/or integrated with) one or more of leg cuffs 112 and/or 114. In some other embodiments, fastening may be achieved via inclusion of one or more laces, ties, cords, and/or other items capable of being tied on one or more of leg cuffs 112 and/or 114. In some instances, a given leg cuff 112/114 may be configured to slide onto a user's leg. In some specific example instances, a given leg cuff 112/114 may be form-fitted to a leg of the user. Other suitable techniques for securing/fastening a given leg cuff 112/114 to a user's leg will depend on a given application and will be apparent in light of this disclosure.

At least one of upper leg cuff 112 and/or lower leg cuff 114 may include, for example, an interconnection 118 there between. In some cases, and in accordance with an embodiment, interconnection 118 may assist with maintaining the positioning of cuffs 112 and 114 on the user's leg such that cuffs 112 and 114 may move independently but remain connected. In some example instances, interconnection 118 may include a cloth webbing material (e.g., a seatbelt-like material, etc.). In some other example instances, interconnection 118 may include a natural and/or synthetic rubber (e.g., neoprene, etc.). In some yet other example instances, interconnection 118 may include fabric straps which may be stitched to, clipped to, or otherwise attached to and/or integrated with cuffs 112 and 114. In some embodiments, interconnection 118 may include, for example, one or more clips, rings, and/or other receiving sites disposed thereon for attaching to and/or slidably guiding resistive element 150.

In some embodiments, a leg binding 110 may be positionable on each of a user's legs. In some such instances, each leg binding 110 on each of the user's legs may include only an upper leg cuff 112, only a lower leg cuff 114, or both an upper leg cuff 112 and a lower leg cuff 114. Numerous suitable configurations will be apparent in light of this disclosure.

In some embodiments, anchoring device 130 may include, for example, an anchoring belt 132 positionable about the user's waist. Anchoring belt 132 may donned and/or secured by the user in any fashion that securely and/or comfortably maintains belt 132 in position. Anchoring belt 132 may include, for example, one or more clips, rings, and/or other receiving sites disposed thereon for attaching to and/or slidably guiding resistive element 150. Resistive element 150 may attach to anchoring belt 132 via one or more connectors 154.

Anchoring device 130 may include an anchoring belt 132, an anchoring harness 134, and/or one or more anchoring shoulder pads 136, as discussed in further detail below with reference to FIG. 5. Any one, two, three, or other combination of these various optional components may be donned by the user to function as anchoring device 130. In some cases, anchoring device 130 may provide minimal or otherwise negligible strain to the user's back and/or neck (e.g., stress to the erector spine muscles) as compared, for example, to an exercise device which only passes around or otherwise anchors to the user's neck.

FIG. 3 is a front perspective view of a mobile exercise device 100 configured in accordance with an embodiment of the present invention. As can be seen, resistive element 150 may include, in some embodiments, a resistive member 152 and a connector 154. Connector 154 may be disposed on one or more ends of resistive member 152 or at any one or more intermediate positions, orientations, and/or locations along the length of resistive member 152. Connector 154 may be, for example, a clip, a strap, a fitted connection, a tie, a carabiner, and/or any other connector capable of coupling resistive member 152 to another portion of device 100.

Resistive member 152 may include, in some embodiments, an elastomeric member. Such elastomeric member may require an application of force, for example, by the user's leg to cause elongation thereof. In the process of elongation, resistive member 152, by virtue of its elastomeric nature, may provide a countering/restoring force opposite the motion of the user's leg. The restoring force may increase and/or decrease linearly, cubically, exponentially, or otherwise, as determined by the design of resistive member 152. In some other embodiments, the restoring force may be constant throughout the path of motion. In some specific example embodiments, resistive member 152 may be configured to cause a restoring force opposite the motion of the leg during the full extension thereof. The form of such an elastomeric member may be, for example, a band, a sheet, a strand, a strap, a braid, and/or a tube, etc. In some instances, the elastomeric member may include one or more of a rubber tube, a bungee or shock cord, and/or a rubber strap.

Resistive member 152 may include, in some embodiments, a spring member. Such a spring member may be any object/material which exhibits elastic characteristics and/or is capable of storing mechanical energy. In the process of elongation, resistive member 152, by virtue of its configuration, may provide a countering/restoring force opposite the motion of the user's leg. The restoring force may increase and/or decrease linearly, cubically, exponentially, or otherwise, as determined by the design of resistive member 152. In some other embodiments, the restoring force may be constant. In some specific example embodiments, resistive member 152 may be configured to cause a restoring force opposite the motion of the leg during the full extension thereof. In some instances, such a spring member may be constructed of metal, plastic, rubber, and/or any other material exhibiting elastic characteristics.

Resistive member 152 may include, in some embodiments, a hydraulic or pneumatic member. Such a hydraulic/pneumatic member may be, for example, in the form of a hydraulic/pneumatic cylinder or other actuator. In accordance with an embodiment, the hydraulic/pneumatic member may be configured to provide countering resistance, for example: (1) only during extension thereof (2) only during compression thereof and/or (3) during both extension and compression thereof. In some instances, the countering resistance may increase and/or decrease linearly, cubically, exponentially, or otherwise, as determined by the configuration of resistive member 152. In some specific example instances, the countering resistance may be constant. In some cases, the hydraulic/pneumatic member may be configured to be single-acting or double-acting.

In some embodiments, connector 154 of resistive element 150 may be configured to connect to, for example, one or more clips, rings, and/or other receiving sites disposed on leg binding 110. In some instances, connector 154 may connect in such fashion with upper leg cuff 112 and/or lower leg cuff 114. Connector 154 may connect, for example, with interconnection 118.

In some embodiments, connector 154 of resistive element 150 may be configured to connect, for example, with one or more clips, rings, and/or other receiving sites disposed on anchoring device 130. In some instances, connector 154 may connect in such fashion with anchoring belt 132, anchoring harness 134, and/or one or more anchoring shoulder pads 136.

Resistive element 150 may be configured, in some embodiments, to pass along at least a portion of the front of the user's torso towards one or more of the user's shoulders. Resistive element 150 may pass along at least a portion of the front of the torso of the user in some embodiments. In some instances, resistive element 150 may pass in a direction substantially parallel with the length of the user's torso. In some other instances, resistive element 150 may cross itself one or more times along the user's torso. In some still other instances, a first resistive element 150 may cross a second resistive element (not shown) one or more times as it passes along the front of the user's torso. In some such embodiments, first resistive element 150 may be of similar and/or different configuration (e.g., resistance; construction; arrangement; etc.) as the second resistive element. In some particular instances, resistive element 150 may crisscross one or more times as it passes along the front of the user's torso. Other suitable arrangements/configurations will depend on a given application and will be apparent in light of this disclosure.

FIG. 4 is a rear perspective view of a mobile exercise device 100 configured in accordance with an embodiment of the present invention. As can be seen, resistive element 150 may be configured, in some embodiments, to pass over one or more of a user's shoulders from a front portion of the user's torso to at least a portion of the rear of the user's torso. Resistive element 150 may attach to one or more portions of anchoring device 130. In some instances, resistive element 150 may attach to anchoring device 130 via one or more connectors 154 disposed on resistive member 152. Anchoring device 130 may be outfitted with one or more corresponding receiving sites for attaching to and/or slidably guiding resistive element 150.

Resistive element 150 may be configured, in some embodiments, to pass along at least a portion of the rear of the user's torso. In some instances, resistive element 150 may pass in a direction substantially parallel with the length of the user's torso. In some other instances, resistive element 150 may cross itself one or more times along the user's torso. In some still other instances, a first resistive element 150 may cross a second resistive element (not shown) one or more times as it passes along the rear of the user's torso. In some such embodiments, first resistive element 150 may be of similar and/or different configuration (e.g., resistance; construction; arrangement; etc.) as the second resistive element. In some particular instances, resistive element 150 may crisscross one or more times as it passes along the rear of the user's torso.

FIG. 5 is a front perspective view of a mobile exercise device 100 configured in accordance with an embodiment of the present invention. As can be seen, in some embodiments, anchoring device 130 may include, for example, an anchoring harness 134 positionable on the user's torso. Anchoring harness 134 may be donned and/or secured by the user without assistance from another. Anchoring harness 134 may include, for example, one or more clips, rings, and/or other receiving sites disposed thereon for attaching to and/or slidably guiding resistive element 150. In some instances, anchoring harness 134 may include, for example, one or more channels 138 disposed thereon for receiving and/or directing resistive element 150 over at least one of the user's shoulders. For instance, such channels 138 may be configured to receive and/or direct resistive element 150 over at least one shoulder of the user towards a rear portion of anchoring harness 134. If anchoring belt 132 is worn simultaneously by the user or is otherwise integral with anchoring harness 134, for example, such channels 138 may receive and/or direct resistive element 150 over at least one shoulder of the user towards a rear portion of anchoring harness 134 and downwardly towards anchoring belt 132.

In some embodiments, anchoring device 130 may include, for example, one or more anchoring shoulder pads 136 positionable on at least one of the user's shoulders. Anchoring shoulder pad 136 may be donned and/or secured by the user to distribute force from the resistive element 150 across the shoulder of the user. Anchoring shoulder pad 136 may include, for example, one or more clips, rings, and/or other receiving sites disposed thereon for attaching to and/or slidably guiding resistive element 150. In some embodiments, such anchoring shoulder pad 136 may include an optional cushion disposed thereon or otherwise be configured to abut/engage a user's shoulder in a cushioned fashion. In some instances, at least one anchoring shoulder pad 136 may include, for example, one or more channels 138 disposed there along for receiving and/or directing resistive element 150 over at least one shoulder of the user. For instance, such channels 138 may be configured to receive and/or direct resistive element 150 over at least one shoulder of the user towards a back portion of anchoring shoulder pad 136. If anchoring belt 132 is worn simultaneously by the user or is otherwise integral with anchoring shoulder pad 136, for example, such channels 138 may receive and/or direct resistive element 150 over at least one shoulder of the user towards a back portion of anchoring shoulder pad 136 and downwardly towards anchoring belt 132.

In some embodiments, resistive element 150 may be a continuous body that passes over one or more shoulders of the user. In some other embodiments, resistive element 150 may be a discontinuous body that passes over one or more shoulders of the user. When discontinuous, resistive element 150 may be attachable and/or operatively coupleable to one or more anchoring shoulder pads 136, which may be configured to move, slide, and/or reposition on the user's torso.

In some embodiments, anchoring device 130 may include both anchoring harness 134 and one or more anchoring shoulder pads 136. In some other instances, anchoring device 130 may include both anchoring harness 134 and anchoring belt 132. In some yet other embodiments, anchoring device 130 may include both anchoring belt 132 and one or more anchoring shoulder pads 136. In some still other instances, anchoring device 130 may include anchoring harness 134, one or more anchoring shoulder pads 136, and anchoring belt 132. In each of the aforementioned arrangements, one or more of the various optional components may be operatively coupled (e.g., physically connected) with another one of such components. In one specific example embodiment, anchoring device 130 may include anchoring harness 134, a pair of anchoring shoulder pads 136 integral with harness 134, and an anchoring belt 132 integral with harness 134, each of which is positionable on the torso of the user.

FIG. 6 is a rear perspective view of a mobile exercise device 100 configured in accordance with an embodiment of the present invention. In some embodiments, mobile exercise device 100 may be configured to permit adjustment of the resistance experienced by the user. As can be seen, adjustment of the resistance level may be achieved by, for example, adjusting a resistance adjustment component 170. Adjustment of resistance adjustment component 170 may occur, for example, by adjusting one or more features integral with component 170 and/or repositioning component 170 on the user. Resistance adjustment component 170 may include, for example, one or more clips, guides, coiling mechanisms, and/or other stowage devices configured to vary the resistance experienced by the user. In some instances, resistance adjustment component 170 may be configured to engage one or more resistive elements 150 different from and/or in addition to the original resistive element 150 in use, thereby changing the resistance experienced by the user. In some other instances, resistance adjustment component 170 may be configured to change the effective length of resistive element 150, thereby changing the resistance experienced by the user. In some specific example embodiments, resistance adjustment component 170 may include, for example, a clip, guide, coiling mechanism, and/or other stowage device positioned on or near anchoring device 130 and configured to change the effective length of resistive element 150.

In some instances, resistance adjustment component 170 may be disposed at one or more positions along resistive element 150, for example. In some further instances, resistance adjustment component 170 may be disposed at one or more positions on any of upper leg cuff 112, lower leg cuff 114, interconnection 118, and/or any other portion of leg binding 110. In some other instances, resistance adjustment component 170 may be disposed at one or more positions on any one or more of anchoring belt 132, anchoring harness 134, anchoring shoulder pad 136, and/or any other portion of anchoring device 130.

In some embodiments, the resistance experienced by the user may be adjusted by including one or more leg bindings 110 configured to be capable of being repositioned along one or more of the user's legs. For instance, upper leg cuff 112 may be repositionable along the entire length of the upper portion of a user's leg or any portion thereof. Similarly, lower leg cuff 114 may be repositionable along the entire length of the lower portion of a user's leg or any portion thereof.

In some embodiments, adjustment of the resistance experienced by the user may be achieved, for example, by exchanging one resistive element 150 for a different resistive element 150 of higher or lower resistance, as desired. In some instances, the exchanged resistive element 150 may be of a different: (1) diameter/width; (2) length; (3) constituent material; and/or (4) any combination thereof. In embodiments including multiple resistive elements 150, a first resistive element 150 may be of similar or different resistance, construction, and/or arrangement from a second resistive element. For example, different resistances may be used on the different legs of the user.

In any given embodiment, adjustment of the resistance experienced by the user may be made with respect to only a first leg, only a second leg, and/or each leg of the user simultaneously. Also, in any given embodiment, adjustment of the resistance experienced by the user may be made prior to use of device 100, during use of device 100, and/or after use of device 100. In some embodiments, adjustment of the resistance level may be performed by the user ex tempore (“on the fly”).

FIG. 7 is a perspective view of a leg binding 110 and resistive element 150 of a mobile exercise device 100, configured in accordance with an embodiment of the present invention. As can be seen, in some cases, upper leg cuff 112 may be positionable on the user's upper leg. Upper leg cuff 112 may be configured to be positioned above the user's knee. Upper leg cuff 112 may be capable of repositioning on the user's upper leg anywhere along the length thereof from the upper thigh to the lower thigh, for example. As upper leg cuff 112 is repositioned from the upper thigh to the lower thigh, the resistance experienced by the user may be made to increase, in some embodiments.

In some cases, lower leg cuff 114 may be positionable on the user's lower leg. Lower leg cuff 114 may be configured to be positioned below the user's knee. Lower leg cuff 112 may be capable of repositioning on the user's lower leg anywhere along the length thereof from the upper shin to the lower shin and/or ankle, for example. As lower leg cuff 114 is repositioned from the upper shin to the lower shin and/or ankle, the resistance experienced by the user may be made to increase, in some embodiments.

In some embodiments in which leg binding 110 is a single cuff, such binding 110 may be positionable on the user's leg. Binding 110 may be configured to be positioned above and/or below the user's knee. Binding 110 may be configured to be positioned above and/or below the user's ankle Binding 110 may be capable of repositioning on the user's upper leg and/or lower leg anywhere along the length thereof from the upper thigh to the lower shin and/or ankle, for example. As binding 110 is repositioned from the upper thigh to the lower shin and/or ankle, the resistance experienced by the user may increase.

In embodiments including both upper leg cuff 112 and lower leg cuff 114, as cuff 112 is positioned further away from cuff 114, interconnection 118, if included, may be capable of adjusting accordingly. In some such instances, sufficient slack in interconnection 118 may be provided to allow cuff 112 and cuff 114 to achieve distal positioning. In some instances, interconnection 118 may be made of an elastic material capable of stretching to a length commensurate with the distal positioning of cuff 112 and cuff 114.

As the user extends the leg (e.g., makes a downward stepping motion) with binding 110 disposed thereon, resistive body 150 correspondingly extends along its length along its path from anchoring device 130 to binding 110. Such extension of resistive element 150 may occur during any portion or the entirety of the range of motion of the leg. Similarly, as the user retracts that leg (e.g., makes an upward stepping motion), resistive body 150 correspondingly compresses/contracts along its length along its path from anchoring device 130 to binding 110. Such compression/contraction of resistive element 150 may occur during any portion or the entirety of the range of motion of the leg. Depending on how resistive body 150 is configured, resistance via a countering/restoring force may be experienced by the user during either or both of the extension and/or retraction motions of the leg.

As the user extends the leg (e.g., makes a downward stepping motion) and/or retracts the leg (e.g., makes an upward stepping motion) with binding 110 disposed thereon, one or more of the user's leg muscles may be engaged. In some instances, the concentric reaction of the gluteus muscles and/or hamstring muscles and/or the eccentric reaction of the hip flexor muscles may be engaged. In some instances, the user's hip joint may be extended. Also, in some instances, use of the device may help to accelerate knee drive and/or provide other hip flexion concentric reaction.

Methodology

FIG. 8 is a flow diagram illustrating an example method of exercising in accordance with an embodiment of the present invention. As can be seen, the method may begin as in block 801, with affixing a resistive element of a given resistance level to a user's leg. The method may continue as in block 803, with passing a portion of the resistive element over the user's shoulder. Next, the method may proceed as in block 805, with anchoring the resistive element to a portion of the user's torso. Thereafter, the method may proceed as in block 807, with causing the user to engage in movement of the leg. It should be noted that the flow diagram of FIG. 8 is not arranged in an invariable order and that numerous variations on this methodology will be apparent in light of this disclosure. For example, in some other embodiments, the method of exercising depicted in FIG. 8 optionally may include affixing the resistive element to each of a user's legs and causing the user to engage in movement of each leg.

Example Implementation Data and Discussion

In each of the example implementations described below, the following example mobile exercise device configuration was used. The user positioned a leg binding, which included both an upper cuff and a lower cuff, on each of his/her legs. The user also positioned a waist belt about his/her torso. A single elastomeric tube was connected to a first of the two leg bindings, directed up the length of the user's chest and over the user's first shoulder, directed down the length of the user's back and anchored to the waist belt, directed back up the length of the user's back and over the user's other shoulder, directed down the length of the user's chest, and connected to the second of the two leg bindings. FIGS. 2 and 3, for example, illustrate a similar configuration.

Experimental use of the device was made by a group of NCAA Division I Field Hockey players, and the results were recorded. The raw data are represented in FIG. 9A (Table 1), and the compared results are represented in FIG. 9B (Table 2). A description of the experimental testing procedure now follows.

First, a baseline test was conducted in which athletes #1-17 had not yet used the device. This baseline test consisted of having each of the athletes #1-17 do a full warm-up and subsequently perform three attempts at a single-leg triple jump and three attempts at a 10-yard dash. The best jump attempt and the best dash attempt for each of athletes #1-17 were recorded, and these raw data for Test #1 are represented in FIG. 9A (Table 1).

Second, each of the athletes #1-17 donned the device and subsequently ran five 20-yard sprints, resulting in a total of 100 yards of sprinting. Each of the athletes then removed the device and stretched briefly.

Third, each of the athletes #1-17 completed the same test as previously used for the baseline measurements, except this time the test was performed after having used the device. Again, each athlete performed three attempts at a single-leg triple jump and three attempts at a 10-yard dash. The best jump attempt and the best dash attempt for each of athletes #1-17 were recorded, and these raw data for Test #2 are represented in FIG. 9A (Table 1).

As a control and as a way to help rule out any learning curve for the single-leg triple jump attempts, experimental use of the device was made by two track and field athletes (labeled ‘C1’ and ‘C2’ in FIGS. 9A-9B) who competed in the single-leg triple jump event on a regular basis for the track team at the school.

First, a baseline test was conducted in which athletes C1 and C2 had not yet used the device. This baseline test consisted of having these athletes do a full warm-up and subsequently perform three attempts at a single-leg triple jump. The best jump attempt of each of athletes C1 and C2 was recorded, and these raw data are represented in FIG. 9A (Table 1).

Second, the track and field athletes C1 and C2 donned the device and subsequently ran five 20-yard sprints, resulting in a total of 100 yards of sprinting. The athletes then removed the device and stretched briefly.

Third, the track and field athletes C1 and C2 completed the same test as previously used for the baseline measurements, except this time the test was performed after having used the device. Again, each athlete performed three attempts at a single-leg triple jump. The best jump attempt of each of athletes C1 and C2 was recorded, and these raw data are represented in FIG. 9A (Table 1).

For the single-leg triple jumps, the total distance of the jump was measured from where the individual athlete started the jump to where the heel of the athlete's foot landed after the third jump.

For the 10-yard dashes, each athlete started in a three-point stance with her hand depressing a pad that, when released (e.g., upon running), started the timer. At the opposite end of the track was an infrared beam that, when crossed by the athlete, stopped the timer.

As can be seen from the compared results in FIG. 9B (Table 2), a marked increase in athletic performance in both the single-leg triple jump and in the 10-yard dash was experienced by the great majority of the users of the device. In FIG. 9B, a positive value in the difference columns pertaining to the single-leg triple jump results represents an increase in the jumping distance achieved by the individual athlete (e.g., an increase in athletic performance). Furthermore, a negative value in the difference columns pertaining to the 10-yard dash results represents a decrease in the dash time achieved by the individual athlete (e.g., an increase in athletic performance).

The results for athletes #1-17 (the group of Field Hockey players) show an average increase in distance of 6 inches (3.34%) for the single-leg triple jump (left), and an average increase in distance of 8 inches (4.04%) for the single-leg triple jump (right). Also, the results for athletes #1-17 show an average decrease in sprint time of 0.06 seconds (2.70%) for the 10-yard dash. Therefore, the data show an overall average increase in athletic performance for athletes 1-17 after having used the device.

The results for athletes C1 and C2 (the control group of track and field athletes) show an average increase in distance of 9 inches (3.08%) for the single-leg triple jump (left), and an average increase in distance of 13 inches (4.81%) for the single-leg triple jump (right). Therefore, the data show an overall average increase in athletic performance for athletes C1 and C2 after having used the device.
